ECCE-CANN builds on a long-term programme of research on cannabis cultivation, drug markets, patterns of use, social perceptions and regulation in Spain and other contexts.

The publications below highlight some of the empirical and conceptual work that provides the foundations for the project.

Historical foundations: policy, culture and markets

A Brief History of Cannabis Policies in Spain (1968–2003)

Gamella, J. F., & Jiménez Rodrigo, M. L. (2004).

Journal of Drug Issues, 34(3), 623–659.

This article provides a historical account of cannabis policies in Spain from the late 1960s to 2003. It examines changes in drug laws and public policies in their demographic, political and economic contexts, following a chronological approach to the transformation of cannabis control.

Comercialización sin legalización: Políticas públicas y consumo/comercio de cannabis en España (1968–2003)

Gamella, J. F., & Jiménez Rodrigo, M. L. (2005).

Revista Española de Drogodependencias, 30(1–2), 17–49.

This article examines the relationship between cannabis policies, consumption and commercialization in Spain from 1968 to 2003. It focuses on the coexistence of relatively favourable legal conditions for cannabis consumption with the expansion of cannabis markets and the contradictions between penal and administrative control, commercialization and patterns of consumption.

The analysis provides an early account of how regulation and commercialization can develop simultaneously rather than as mutually exclusive processes.

From previous research to ECCE-CANN

Taken together, this body of research traces a long-term trajectory of research on cannabis in Spain: from the historical transformation of drug policies and the emergence of cannabis culture, through markets, transnational circulation and cultivation systems, to contemporary questions of regulation and contested legality.

ECCE-CANN builds on this research while shifting the analytical focus towards the relations connecting cultivation practices, people, materials, knowledge, labour, technologies, markets, infrastructures and institutions.
